Exercising Your Gut Microbiome with Darryl Edwards
'When I found myself teetering on the edge of prediabetes, I knew I needed to make a change. I chose movement, and it changed my life.' - On our latest episode, we discuss this journey with Darryl Edwards, a movement coach and author, who made this transformation. From a fascinating conversation about the Primal Play Method to an enlightening discussion on the transformative power of exercise on the gut microbiome, this episode is full of insights and inspiration.We also delve into fascinating research on the effects of exercise on our gut health. Darryl and I explore interesting animal studies that show how physical activity can boost the presence of beneficial bacteria and reduce the number of harmful ones. We discuss how diet and other factors associated with athleticism can enhance these benefits. We also touch on the importance of nutrition for athletes, especially in relation to energy expenditure, mitochondrial function, and the production of short-chain fatty acids.Finally, we explore the implications of modern sedentary lifestyles on our health and gut microbiomes. From the evolution of furniture to the advancement of technology, we discuss how our environments encourage inactivity. But it's never too late to make a change. Whether it's introducing exercise early in life, opting for outdoor activities like gardening, or just learning to move more, every step towards a more active lifestyle can have profound impacts on our health and gut microbiomes. So, join us on this journey of discovery and learn how to reclaim the joy of movement!https://www.primalplay.com/blog/unlock-the-power-of-play-how-active-play-boosts-adult-health-happinessThis podcast is brought to you in collaboration with the British Society of Lifestyle Medicine.Disclaimer:The content in this podcast is not intended to be a substitute for professional medical advice, diagnosis, or treatment.

Microbiotoxicity: Bridging the Gap Between Microbiome Research and Clinical Practice with Dr Anastasia Theodosiou
In this podcast episode, Dr Sheena Fraser and Dr Siobhan Mccormack (aka Microbiome Medics) discuss the significant impact of antibiotics on the gut microbiome. They are joined by an expert in this area Dr Anastasia Theodosiou, who is both a Microbiome Scientist and a Registar in Microbiology & Infectious Disease.Dr Anastasia introduces her novel term Microbiotoxicity which can be used to explain and predict the effects of antibiotics on human microbiomes. The discussion also covers other drugs like proton pump inhibitors and selective serotonin reuptake inhibitors (SSRIs) which can also perturb the gut microbiome. Listeners will gain insights into the recovery timeline of the gut microbiome after antibiotic exposure and the implications of gut microbiome disruptors like Caesarian section delivery and neonatal formula feeding on both gut health and other health outcomes across the lifespan. This episode highlights the importance considering the impact of medications on the gut microbiome and how we might start to bridge the gap between microbiome research and clinical practice.Dr Theodosiou is an MRC Clinical Research Training Fellow (University of Southampton) and an Infectious Diseases and Medical Microbiology Registrar. Her research involves the use of controlled human infection to study microbiome development in early life, including the world’s first respiratory human challenge study in pregnancy.https://idiotspodcasting.buzzsprout.com/1782416/13193172-56-antibiotics-breastfeeding-and-infant-healthTheodosiou AA, Jones CE, Read RC, Bogaert D.

Cancer and the Gut Microbiome Part 3: Revolutionizing Cancer Outcomes through Gut Microbiome Research
In this 3rd & final episode Dr Sheena & Dr Shiv get to chat to Professor Robert Thomas , a full time NHS Consultant Oncologist, Sorts and Nutrition scientist and active medical researcher who explains why he thinks the gut microbiome and gut health are key to cancer prevention, response cancer therapies and survivorship.They discuss diet, research and patient empowerment. It seems that small, simple , achievable dietary and behaviour changes really can improve outcomes , overall wellbeing and survivorship. Professor Robert Thomas is a full time NHS Consultant Oncologist at Bedford and Addenbrooke's Hospitals, a teacher at Cambridge University and visiting Professor of Sports and nutritional science at the University of Bedfordshire. He trained at the Royal Marsden Hospital had period of full-time laboratory and clinical research at the Institute of Cancer and Duke University, North Carolina. He now manages patients with chemotherapy, radiotherapy, hormones and biological targeted treatments but incorporates nutritional and lifestyle strategies to enhance their effect, reduce side effects and improve overall wellbeing.He is also head of a Lifestyle and Cancer Research Unit which designs and conducts government backed studies evaluating the impact of exercise, diet and natural therapies on cancer, other chronic diseases and more recently recovery from Covid-19. In collaboration with Universities in Southern California, Cambridge and Glasgow, this unit has published over 100 peer reviewed scientific papers and regularly presents studies across the World. He is a patron of two cancer support charities and advises Macmillan and other support groups on their informal materials for patients.He previously led the UK Polybalm and Pomi-T randomised studies and currently leads the UK's covid-19 nutritional intervention study (The Phyto-V study) assessing whether prebiotic polyphenol rich foods plus a probiotic could lower the severity and duration of symptoms.He is author of the UK bestseller "How to Live" and has been awarded The British Oncology Association “Oncologist of the Year” and The Royal College of Radiologist Research Medal.Twitter: @cancernetUKFacebook: @cancernetUKThis podcast is brought to you in collaboration with the British Society of Lifestyle Medicine.Disclaimer:The content in this podcast is not intended to be a substitute for professional medical advice, diagnosis, or treatment.
